| 1 | Clostridium difficile infections in China显示文摘Clostridium difficile (C. difficile) infection has become one of the major hospital-associated infections in West-ern countries in the last two decades. However, there is limited information on the status of C. difficile infection inChinese healthcare settings. Given the large and increasing elderly population and the well-recognized problem ofover-prescribing of broad spectrum antibiotics in China, it is critical to understand the epidemiology and potentialrisk factors that may contribute to C. difficile infection in China. A literature review of available published studies,including those in Chinese language-based journals, was conducted. A review of the currently available literaturesuggested the presence of C. difficile infections in China, but also suggested that these infections were not particu-larly endemic. This finding should lead to better designed and greatly expanded studies to provide a more reliableepidemiologically-based conclusion on the actual status of C. difficile infection in China, including the identifica-tion of any associated risk factors. Such information is ultimately valuable to develop appropriate strategies to pre-vent C. difficile infection and the vast negative impact of such infections in China and other developing countries. | Ke Jin a,b,c,Shixia Wang c,d,Zuhu Huang a,b,c,Shan Lu b,c,daDepartment of Infectious Diseases,bJiangsu Province Key Laboratory in Infectious Diseases,cChina-US Vaccine ResearchCenter,the First Affiliated Hospital of Nanjing Medical University,Nanjing,Jiangsu 210029,China d Department of Medicine,University of Massachusetts Medical School,Worcester,MA 01655,USA. | 2010 | The Journal of Biomedical Research2010，24，6： | 14 |

| 4 | ^137Cs tracing dynamics of soil erosion,organic carbon,and total nitrogen in terraced fields and forestland in the Middle Mountains of Nepal显示文摘The Middle Mountains is one of the regions of Nepal most vulnerable to water erosion, where fragile geology, steep topography, anomalous climatic conditions, and intensive human activity have resulted in serious soil erosion and enhanced land degradation. Based on the 137 Cs tracing method, spatial variations in soil erosion, organic carbon, and total nitrogen(TN) in terraced fields lacking field banks and forestland were determined. Soil samples were collected at approximately 5 m and 20 m intervals along terraced field series and forestland transects respectively. Mean 137 Cs inventories of the four soil cores from the reference site was estimated at 574.33 ± 126.22 Bq m-2(1 Bq(i.e., one Becquerel) is equal to 1 disintegration per second(1 dps)). For each terrace, the 137 Cs inventory generally increased fromupper to lower slope positions, accompanied by a decrease in the soil erosion rate. Along the entire terraced toposequence, 137 Cs data showed that abrupt changes in soil erosion rates could occur between the lower part of the upper terrace and the upper part of the immediate terrace within a small distance. This result indicated that tillage erosion is also a dominant erosion type in the sloping farmland of this area. At the same time, we observed a fluctuant decrease in soil erosion rates for the whole terraced toposequence as well as a net deposition at the toe terrace. Although steep terraces(lacking banks and hedgerows) to some extent could act to limit soil sediment accumulation in catchments, soil erosion in the terraced field was determined to be serious. For forestland, with the exception of serious soil erosion that had taken place at the top of slopes due to concentrated flows from a country road situated above the forestland site, spatialvariation in soil erosion was similar to the 'standard' water erosion model. Soil organic carbon(SOC) and TN inventories showed similar spatial patterns to the 137 Cs inventory for both toposequences investigated. However, due to the different dominant erosion processes between the two, we found similar patterns between the <0.002 mm soil particle size fraction(clay sized) and 137 Cs inventories in terraced fields, while different patterns could be found between 137 Cs inventories and the <0.002 mm soil particle size fraction in the forestland site. Such results confirm that 137 Cs can successfully trace soil erosion, SOC and soil nitrogen dynamics in steep terraced fields and forestland in the Middle Mountains of Nepal. | SU Zheng-an XIONG Dong-hong DENG Wei DONG Yi-fan MA Jing PADMA C Poudel GURUNG B Sher | 2016 | Journal of Mountain Science2016，13，10： | 4 |
| 5 | Variations in Wool Growth with Nutrient Supply in Northern China显示文摘Field studies on essessment of nutritional status of the grazing sheep were carried out in each of the three major grassland regions, the eastern Inner Mongolia and beyond grassland, the Inner Mongolia - Ningxia - Gansu grassland and the Xinjiang grassland, in northern China. The results obtained showed that the wool production of fine wool sheep in these regions varied between regions and seasons, with similar seasonal patterns in all regions and that reducing the seasonal variations in nutrient supply would enhance wool production substantially. Nutritional limitations to wool growth of the grazing sheep in these regions were suggested, those were: the shortage of protein supply in winter and early spring; the poor quality of much of the pasture and the hay used as supplements, the low energy intake during winter which probably necessitated the use of body stores to maintain body temperature. | D X Lu,Iner(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)Z C Feng,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)H R Wang,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)R Z Yang,(Xinjiang Institute of Animal Science.Xinjiang Academy of Animal Science.Yiu Hou Road.Urumqi.Xinjiang Uygur Autonomous Region PRC)C T Ma,(Chinese Academy of Agricultural Sciences.Lanzhou.Gansu.PRC)D B Purser,(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)J R Lindsay(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)D W Peter(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014) | 1997 | 畜牧与饲料科学1997，22，S1： | 3 |
